The prognostic value of cell surface antigens in low grade, non-invasive, transitional cell carcinoma of the bladder. | Tumors in 23 patients who presented with a low grade, non-invasive transitional cell carcinoma of the bladder were studied for blood group antigens A, B or O on the cell surface. Of 14 patients without cell surface antigens initially 13 suffered an invasive tumor subsequently and 1 had diffuse carcinoma in situ. Of 9 p... | 480,485 | [

[Sympathetic control on salivary secretion by the parotid gland in rabbit. I. Effects on the unstimulated gland (author's transl)]. | The sympathetic influences on the rabbit unstimulated parotid gland were studied. The experiments were carried out in anaesthetized rabbits with the Stenon aduct cannulated. Direct stimulation of the superior cervical ganglion elicits variable salivary flows. The high amylase content in the saliva points to a sympathet... | 482,720 | [
